Aerodynamics of a car with no hood?

[goatnipples2002]

I have a 94 Mustang with 351w and a big turbo. This is a street car. I didn't have room for my 2nd turbo setup, so I removed my hood and put the turbo in "clean" air (kinda ram air style). I also did this to let the heat out. 

I read a post on another scta forum that they tested a camaro with and without the hood.

"For what it's worth, we tested our Bonneville Camaro in the wind tunnel with and without a hood. The cd number changes a little--probably not enough to matter at 100 mph--but the front lift number reduces..."

With my car making 600ish rwhp less lift is a good thing, but is the cost worth the payoff?

I was told not to worry about the front of the car, but the rear was more important...opinion?

I thought that adding a sheetmetal lip spoiler to the front of the car above the radiator to help direct the air over the engine bay might help with downforce and aerodynamics. I was told I would be hurting myself worse and I would only introduce more drag...opinions?

Us backwoods folk are familiar with the no hood concept as well as the no door one.  It gets rather dicey when you split a radiator hose or something else and the windshield is covered with spooge and you cannot see through it.

Leave it on.

I sold the hood last year. This is year 2 with no hood and no probs yet.

I figured I could get some scientific help. Hell I got better responces from the Mustang guys.

Maybe 'cause all our ponies are required to have hoods.

I can understand that...just hoping someone may have some insight.

The only way to know is to put it in the wind tunnel and test it.  Just because it didn't make a large difference on a Camaro doesn't mean anything to your Mustang.  The pony could lift more without the hood, only testing will tell. 
If you want to run it without a hood on the street, then by all means do so.  If you want to race it, check with the organization to ensure they allow it in your class. 
Aero affects both ends and the middle

Why not post a couple of pictures so we can see what you are talking about.  You are not going to get anything but wild imagination if you make everyone use their wild imagination

Any negative aero measurable at 100 will be astronomical at 200.
